Which body is responsible for managing the affairs and property of FBLA?

The Board of Directors is responsible for managing the affairs and property of FBLA (Future Business Leaders of America). This body comprises elected members who oversee the organization's strategic direction, financial decisions, and overall governance. Their role is critical in ensuring that FBLA operates effectively and fulfills its mission to enhance business education through various programs and resources.

In contrast, other entities such as the National Board of Advisors, State Coordinators, and Local Chapters play supportive or operational roles within the organization. The National Board of Advisors provides guidance and support but does not manage the organization's property. State Coordinators facilitate programs at the state level, while Local Chapters operate at the community level, focusing on the implementation of FBLA programs and activities. Thus, the Board of Directors holds the primary responsibility for managing organizational affairs, making it the correct answer.
